Post-processing online analysis device and glove box system

The invention discloses a post-processing online analysis device and a glove box system, which are used for reducing the self-absorption of feed liquid when primary X-rays penetrate through the feed liquid, improving the excitation efficiency of the primary X-rays and improving the detection precision of a detector. The post-processing online analysis device comprises a flow cell main body (2), an X-ray tube (17) and a detector (15). And the flow cell main body (2) is arranged in a glove box. A flow cell window (4) is formed in the side wall of the flow cell main body (2), the position of the flow cell window (4) corresponds to that of a glove box window (6) of the glove box, and the flow cell window (4) and the glove box window (6) are both made of light-transmitting light materials. And an X-ray tube (17) is arranged outside the glove box. A detector (15) is arranged outside the glove box, and the detector (15) and the X-ray tube (17) are positioned on the same side of the flow cell main body (2). 本发明公开了一种后
